The PY32 offline programmer currently supports chip models in the PY32F002A/002B/002/003/030/071/072/040/403/303 packages and XL32F001/003. The PY32 offline programmer uses a MINI-USB interface, providing a stable physical connection. The device communicates with the computer via a serial port, with a fixed baud rate of 1M. It must be used in conjunction with our host software. The … Read more
Introduction: UART is a universal serial data bus used for asynchronous communication. This bus supports bidirectional communication, enabling full-duplex transmission and reception. UART is commonly used for data communication with PCs, as well as for the transmission of command and control information. In this article, we will introduce the UART communication protocol, transmission timing, and … Read more
